Fireplace Doors Guide

Tempered Glass

Fireplace glass doors come equipped with a specially tempered glass that is designed to withstand high temperatures. Tempered glass is actually normal glass that has been heat treated to make it stronger. It can hold up to the thermal shock of high temperatures, and has the ability to reduce injury because of its breakage pattern.

Tempered glass used in fireplace doors is rated to withstand temperatures of up to 500 degrees for sustained periods of time, making it a perfect fit for your fireplace. While tempered glass does a nice job of withstanding high temperatures, it can break if exposed to direct contact with flame. As a general rule of thumb, it is a good idea to keep flames at least four inches from your fireplace glass doors.

Tempered glass also breaks different than regular glass. Instead of splintering into long jagged pieces like normal glass, an entire piece of tempered glass will fragment into small pieces. Fireplace glass doors are typically built with ¼” thick tempered glass, and are available in clear, bronze tint, gray tint, or mirrored options. Tempered glass can also be etched and or beveled for an extra design flair.
